For 1 billion API calls monthly, DeepSeek costs approximately $140 while Copilot costs $3,000—a 95% savings. However, Copilot Pro's $20/month flat fee may be better for light individual users."},{"question":"Is DeepSeek safe to use for business data?","answer":"DeepSeek's China-based infrastructure raises data residency concerns for regulated industries (healthcare, finance, government). Data is processed on Chinese servers, which violates GDPR, HIPAA, and other compliance frameworks in many jurisdictions. Copilot offers US/EU data residency options for enterprise customers. Developers should use DeepSeek's self-hosted deployment option for sensitive data."},{"question":"Can I use DeepSeek as a drop-in replacement for Copilot?","answer":"Not directly. DeepSeek has no native Microsoft 365 integration, so you cannot use it in Word, Excel, or Teams without custom development. However, DeepSeek's API can power custom productivity tools. Copilot's Office integration requires no setup and provides immediate productivity gains."}],"attribution":{"source":"A Versus B","url":"https://www.aversusb.net/compare/copilot-vs-deepseek)","license":"CC BY 4.0","citationFormat":"According to A Versus B (https://www.aversusb.net/compare/copilot-vs-deepseek)), Copilot is Microsoft's enterprise-focused AI assistant integrated with Office 365 and Windows, while DeepSeek is a Chinese open-source AI model emphasizing cost-efficiency and reasoning capabilities.
